How to Connect Inverter to Distribution Board?

How To Connect Inverter To Distribution Board South Africa? Connecting an inverter to a distribution board is a common requirement for homeowners looking to power appliances during load-shedding. However, the process requires a thorough understanding of electrical systems and careful execution to ensure safety and efficiency.

Inverters convert direct current (DC) into alternating current (AC). A properly installed inverter will help you reduce your dependence on the grid, thus lowering electricity bills over time.

Check the DB Board’s Capacity:

With load-shedding becoming an increasing issue in South Africa, people are looking for backup power solutions that can help keep lights and systems running during outages. One of the best options available is an inverter system that can be connected to a DB board to provide power during outages. However, before you start connecting an inverter to your DB board, it’s important to take some time to assess the system’s capacity and make any necessary upgrades.

A DB board is the electrical component that powers your household appliances and devices. It converts DC power from batteries into AC power that can be used to run lighting and plugs. Inverters connect to DB boards to allow individuals to enjoy uninterrupted power and utilize renewable energy sources, helping them reduce their reliance on the grid and save on electricity bills over time. The process of connecting an inverter to a DB board is relatively simple and straightforward, but it’s crucial to follow the correct steps and ensure safety precautions are taken when working with electrical components.

Prepare the Wires:

While it may seem straightforward, connecting an inverter to a distribution board requires the right skills and a meticulous approach. Failure to do so can result in electrical mishaps and unnecessary expenses.

This comprehensive guide will equip you with the knowledge and tools needed to wire your inverter properly. It will cover everything from the necessary components to the step-by-step process. You’ll also learn about common troubleshooting scenarios and their solutions.


Before you begin, it’s important to prepare your wiring circuits. Ensure that the gauge of your wires is adequate to handle the maximum load of your inverter and the charging current of your batteries. You’ll also need to strip the insulation at the ends of each wire to expose its conductive core.

Also, keep in mind that it’s best to consult with a professional electrician when installing an inverter. They will have the required experience and knowledge to ensure a smooth, safe, and efficient installation. They will also be able to recommend the right components for your power system and install manual cut-over switches and fuse boxes, which can help reduce the risk of electrical faults.

Perform Load Separation:

Before connecting an inverter to a distribution board, it’s important to perform load separation. This process ensures that the inverter is not overloading the grid and that any devices connected to it can run without the risk of tripping the circuit breaker. It also prevents backfeeding into the grid from the inverter.

To carry out load separation, shut off the power supply to your DB board and disconnect any power sources you’re using. Then, identify the input and output terminals of the inverter. Make sure to use wires of an adequate gauge to handle the inverter’s current output and charging current.

It’s also advisable to install fuse boxes on your DB board to protect the electrical circuits from overloading and short-circuiting. These installations are essential for the safety of your appliances and inverter. Moreover, they ensure that the wiring system meets SANS specifications. It is also necessary to consult a professional if you encounter complicated wiring issues or problems with your inverter’s compatibility with the existing DB board.

Connect the Inverter:

If you have a battery-based power system, it’s crucial that you know how to connect your inverter to the distribution board. This process allows you to use appliances and lights during power outages or in off-grid situations. It’s also helpful for avoiding any electrical problems, such as blown fuses or tripped breakers. However, the actual connection process may vary based on your equipment and distribution board.

Before you begin working, make sure to turn off the main power supply. Also, work in a well-ventilated area to prevent overheating. You should also check the inverter and battery for any signs of damage or wear. If you notice any of these issues, consult with a professional electrician for assistance.

An inverter is a device that converts DC (direct current) power from batteries into AC (alternating current) power to run appliances and lights. It can also be connected to a solar system for off-grid use. In addition, it can regulate current from a solar system and the grid feeding into the home.

Ground the Inverter:

The inverter and distribution board form the backbone of your alternative power system, providing a safe and reliable way to run your appliances. The proper connection of these two components is crucial to ensure that your inverter can provide the required amount of energy. This process is also necessary to prevent any electrical mishaps.

In addition, you should make sure that your inverter’s charging and output connections comply with SANS specifications. This includes a separate neutral bar for the inverter output and the use of battery fuses. In addition, you should install manual cut-over switches and fuse boxes to protect against faulty appliances.

If you’re experiencing frequent tripping of your circuit breakers, it could be due to overloading or a fault within your system. In this case, you should consult a professional to determine what the cause is and how to remedy it. Taking the right steps and using recommended components will help you properly connect your inverter to a DB board. Always prioritize safety and seek the assistance of a certified electrician when working with electricity.
